Build Abstract (Parent) Shader
Add a reroute beween your principled BSDF and your texture
Select both the bsdf and the reroute
Go to Add > Group > Make Group (CTRL + G )
Link the group input to your color and delete the reroute





Go back to the shader with TAB or the arrow in the top right
Now you can plug your image in the group
Create another shader, delete the principled, add your group with Add > Group > NodeGroup and plug your other card image
Example with procedural textures but it can be used with image textures :




Note the "2" on the right of the name of the node group. That means that it currently has 2 users. If you want to make a hard copy and edit it independently, click on the number and the name should change. The resulting node group will not be shared with the other ones.

If you want to tweak the roughness for example, select the node group and tap TAB to edit it.
